使用chai测试期间无法将错误与throw匹配

我正在尝试编写一个捕获错误的测试用例“错误：请提供pitchWidth和pitchHeight”。但我似乎无法将这一投射作为一次成功的测试。

码：

mocha.describe('testValidationOfBadInputData()', function() {
mocha.it('init game fails on pitch height', async() => {
  let t1location = './init_config/team1.json'
  let t2location = './init_config/team2.json'
  let plocation = './test/input/badInput/badPitchHeight.json'
  // let badFn = await validation.initGame(t1location, t2location, plocation)

  expect(await validation.initGame(t1location, t2location, plocation)).to.throw()
}) })

输出：

1) testValidationOfBadInputData()
       init game fails on pitch height:
     Error: Please provide pitchWidth and pitchHeight
      at Object.validatePitch (lib/validate.js:56:11)
      at Object.initiateGame (engine.js:18:12)
      at Object.initGame (test/lib/validate_tests.js:9:29)       

其他尝试也失败了：

1)

expect(await validation.initGame(t1location, t2location, plocation)).to.throw(Error, 'Please provide pitchWidth and pitchHeight');

2)

expect(await validation.initGame.bind(t1location, t2location, plocation)).to.throw();

不知道我做错了什么，文档似乎并不明显。

async function initGame(t1, t2, p) {       
  let team1 = await common.readFile(t1)       
  let team2 = await common.readFile(t2)       
  let pitch = await common.readFile(p)       
  let matchSetup = engine.initiateGame(team1, team2, pitch)     
 return matchSetup  
}

以上是我打电话的功能。

我认为这看起来类似于我昨天遇到的一个问题并且与这个问题相符：Is node's assert.throws completely broken?

该函数在传递给expect（）之前在堆栈中执行。

而是试试

expect(function() { await validation.initGame(t1location, t2location, plocation); }).to.throw()
